First full test of all functionality. Some typos fixed in TTYserial / xbeeDMapi
This will be merged into master when finished.
Fixed timing error in readerMain and added sleep in w_tty.
Fixed error in sendPkt() and added error checking for ATND in xbmain.cpp
Fixed error in ATNDPkt(). Didn't have correct frame ID.
Fixed xbeeNeighbor::remove()'s return values.
Fixed TX status, testing unicast.
Fixed typo in unicast code in xbmain.cpp
Final testing update. All functions/classes/methods work as expected.
Will now merge testing with main, after this testing commit.

The following tests were made:

broadcast packets (sent / received / tx status looked for)
unicast packets (sent / received / tx status looked for)
AT-ND packet
Neighbor found & functionality of xbeeNeighbor class

After this test, the code is considered basically ready for large file stream
testing.
